Abstract

In order to determine the solid solubility of Ag in YBa₂Cu₃O_6+y and its effect on superconducting properties, a series of YBa₂Cu_3-xAg_xO_6+y samples (x≤0.75) have been prepared and characterized by X-ray diffraction, optic al microscopy, and electron microprobe analysis. The central results are that Ag goes into solid solution up to about x=0.06 and that initially (up to x=0.035) superconducting properties are improved - T_c goes up by 1.1 K, intragrain critical current density is marginally improved and Meissner effect is considerably enhanced. However, at higher x all the superconducting properties are considerably degraded. The implication of these results on the use of Ag as a cladding material for 123 or in a composite are discussed.
